Executive Summary The Airoha App Driver refers to the proprietary software interface and hardware abstraction layer (HAL) used to communicate with Airoha Technology’s line of chipsets, primarily Bluetooth SoCs (e.g., AB15xx, AB156x, AB160x series). This driver is critical for host processors (e.g., Qualcomm, MediaTek, or a separate MCU) to manage audio codec settings, RF parameters, power management, and vendor-specific commands.
The driver is not a standard Linux kernel driver but a vendor-specific, often RTOS-oriented, library that exposes an API for controlling Airoha chips in consumer electronics (TWS earbuds, smart speakers). 2. System Architecture The Airoha App Driver sits between the Host Application (e.g., audio player, call manager) and the Airoha Hardware . airoha app driver
